How can PHP developers effectively manage external dependencies and tools for network scanning?
PHP developers can effectively manage external dependencies and tools for network scanning by using a package manager like Composer to handle the installation and updates of necessary libraries. By defining dependencies in a composer.json file and running `composer install`, developers can easily manage and update the required tools for network scanning.
// composer.json
{
"require": {
"vendor/package": "^1.0"
}
}
```
// Run `composer install` to install the dependencies
```bash
composer install
